Here's another interesting audio illusion. Play the clip several times, alternating between looking at the talking head while listening, and listening with your eyes shut. Most adults (98%) think they are hearing "DA" - a so called "fused respons" - where the "D" is a result of an audio-visual illusion. In reality you are hearing the sound "BA", while you are looking at the lip movements "GA". It's called the McGurk effect.
